Call _me_ to listen to some **awesome** music, or send /call to make _me_ call _you_ (don't forget to disable call privacy settings!).

You can also program a phone call with /program:

/program 29 August 2018 - call me the 29th of august 2018
/program +1 hour 30 minutes - call me in one hour and thirty minutes
/program next Thursday - call me next Thursday at midnight

Send /start to see this message again.

I also provide advanced stats during calls!
